In the Linux kernel, the following vulnerability has been resolved:

drm/amdgpu/vce: fix integer overflow in image size

Fix a security vulnerability where malicious VCE command streams

with oversized dimensions (e.g. 65536×65536) cause 32-bit integer

overflow, wrapping the calculated buffer size to 0. This bypasses

validation and allows GPU firmware to perform out-of-bound memory

access.

The fix uses 64-bit arithmetic to detect overflow and rejects

invalid dimensions before they reach the hardware.

V2: remove redundant check

V3: modify max height value

V4: remove size64

(cherry picked from commit cbe408dba581755ad1279a487ec786d8927d778d) (NVD)
